Field of Technology
[0001] The present disclosure relates to electronic devices, including but not limited to,
portable electronic devices having touch-sensitive displays and their control.
Background
[0002] Electronic devices, including portable electronic devices, have gained widespread
use and may provide a variety of functions including, for example, telephonic, electronic
messaging and other personal information manager (PIM) application functions. Portable
electronic devices include, for example, several types of mobile stations such as
simple cellular telephones, smart phones, wireless personal digital assistants (PDAs),
and laptop computers with wireless 802.11 or Bluetooth capabilities.
[0003] Portable electronic devices such as PDAs or smart telephones are generally intended
for handheld use and ease of portability. Smaller devices are generally desirable
for portability. A touch-sensitive display, also known as a touchscreen display, is
particularly useful on handheld devices, which are small and have limited space for
user input and output. The information displayed on the touch-sensitive displays may
be modified depending on the functions and operations being performed. With continued
demand for decreased size of portable electronic devices, touch-sensitive displays
continue to decrease in size. Improvements in devices with touch-sensitive displays
are desirable.

[0009] For simplicity and clarity of illustration, reference numerals may be repeated among
the figures to indicate corresponding or analogous elements. Numerous details are
set forth to provide an understanding of the examples described herein. The examples
may be practiced without these details. In other instances, well-known methods, procedures,
and components are not described in detail to avoid obscuring the examples described.
The description is not to be considered as limited to the scope of the examples described
herein.
[0010] The disclosure generally relates to an electronic device, such as a portable electronic
device or non-portable electronic device. Examples of portable electronic devices
include mobile, or handheld, wireless communication devices such as pagers, cellular
phones, cellular smart-phones, wireless organizers, personal digital assistants, wirelessly
enabled notebook computers, tablet computers, mobile internet devices, electronic
navigation devices, and so forth. The portable electronic device may be a portable
electronic device without wireless communication capabilities, such as handheld electronic
games, digital photograph albums, digital cameras, media players, e-book readers,
and so forth. Examples of non portable electronic devices include desktop computers,
electronic white boards, smart boards utilized for collaboration, built-in monitors
or displays in furniture or appliances, and so forth.
[0011] A block diagram of an example of a portable electronic device 100 is shown in FIG.
1. The portable electronic device 100 includes multiple components, such as a processor
102 that controls the overall operation of the portable electronic device 100. Communication
functions, including data and voice communications, are performed through a communication
subsystem 104. Data received by the portable electronic device 100 is decompressed
and decrypted by a decoder 106. The communication subsystem 104 receives messages
from and sends messages to a wireless network 150. The wireless network 150 may be
any type of wireless network, including, but not limited to, data wireless networks,
voice wireless networks, and networks that support both voice and data communications.
A power source 142, such as one or more rechargeable batteries or a port to an external
power supply, powers the portable electronic device 100.
[0012] The processor 102 interacts with other components, such as a Random Access Memory
(RAM) 108, memory 110, a touch-sensitive display 118, one or more actuators 120, one
or more force sensors 122, an auxiliary input/output (I/O) subsystem 124, a data port
126, a speaker 128, a microphone 130, short-range communications 132 and other device
subsystems 134. The touch-sensitive display 118 includes a display 112 and touch sensors
114 that are coupled to at least one controller 116 that is utilized to interact with
the processor 102. Input via a graphical user interface is provided via the touch-sensitive
display 118. Information, such as text, characters, symbols, images, icons, and other
items that may be displayed or rendered on a portable electronic device, is displayed
on the touch-sensitive display 118 via the processor 102. The processor 102 may also
interact with an accelerometer 136 that may be utilized to detect direction of gravitational
forces or gravity-induced reaction forces.
[0013] To identify a subscriber for network access, the portable electronic device 100 may
utilize a Subscriber Identity Module or a Removable User Identity Module (SIM/RUIM)
card 138 for communication with a network, such as the wireless network 150. Alternatively,
user identification information may be programmed into memory 110.
[0014] The portable electronic device 100 includes an operating system 146 and software
programs, applications, or components 148 that are executed by the processor 102 and
are typically stored in a persistent, updatable store such as the memory 110. Additional
applications or programs may be loaded onto the portable electronic device 100 through
the wireless network 150, the auxiliary I/O subsystem 124, the data port 126, the
short-range communications subsystem 132, or any other suitable subsystem 134.
[0015] A received signal such as a text message, an e-mail message, or web page download
is processed by the communication subsystem 104 and input to the processor 102. The
processor 102 processes the received signal for output to the display 112 and/or to
the auxiliary I/O subsystem 124. A subscriber may generate data items, for example
e-mail messages, which may be transmitted over the wireless network 150 through the
communication subsystem 104. For voice communications, the overall operation of the
portable electronic device 100 is similar. The speaker 128 outputs audible information
converted from electrical signals, and the microphone 130 converts audible information
into electrical signals for processing.
[0016] The touch-sensitive display 118 may be a capacitive touch-sensitive display that
includes capacitive touch sensors 114. The capacitive touch sensors may comprise any
suitable material, such as indium tin oxide (ITO).
[0017] One or more touches, also known as touch contacts or touch events, may be detected
by the touch-sensitive display 118. The processor 102 may determine attributes of
the touch, including a location of the touch. Touch location data may include data
for an area of contact or data for a single point of contact, such as a point at or
near a center of the area of contact. The location of a detected touch may include
x and y components, e.g., horizontal and vertical components, respectively, with respect
to one's view of the touch-sensitive display 118. A touch may be detected from any
suitable input member, such as a finger, thumb, appendage, or other objects, for example,
a stylus, pen, or other pointer, depending on the nature of the touch-sensitive display
118. Multiple simultaneous touches may be detected.
[0018] One or more gestures may also be detected by the touch-sensitive display 118. A gesture,
such as a swipe, also known as a flick, is a particular type of touch on a touch-sensitive
display 118 and may begin at an origin point and continue to an end point, for example,
a concluding end of the gesture. A gesture may be identified by attributes of the
gesture, including the origin point, the end point, the distance travelled, the duration,
the velocity, and the direction, for example. A gesture may be long or short in distance
and/or duration. Two points of the gesture may be utilized to determine a direction
of the gesture. A gesture may also include a hover. A hover may be a touch at a location
that is generally unchanged over a period of time or is associated with the same selection
item for a period of time.
[0019] The optional actuator(s) 120 may be depressed or activated by applying sufficient
force to the touch-sensitive display 118 to overcome the actuation force of the actuator
120. The actuator(s) 120 may be actuated by pressing anywhere on the touch-sensitive
display 118. The actuator(s) 120 may provide input to the processor 102 when actuated.
Actuation of the actuator(s) 120 may result in provision of tactile feedback. When
force is applied, the touch-sensitive display 118 is depressible, pivotable, and/or
movable. Such a force may actuate the actuator(s) 120. The touch-sensitive display
118 may, for example, float with respect to the housing of the portable electronic
device, i.e., the touch-sensitive display 118 may not be fastened to the housing.
A mechanical dome switch actuator may be utilized. In this example, tactile feedback
is provided when the dome collapses due to imparted force and when the dome returns
to the rest position after release of the switch. Alternatively, the actuator 120
may comprise one or more piezoelectric (piezo) devices that provide tactile feedback
for the touch-sensitive display 118.
[0020] Optional force sensors 122 may be disposed in conjunction with the touch-sensitive
display 118 to determine or react to forces applied to the touch-sensitive display
118. The force sensor 122 may be disposed in line with a piezo actuator 120. The force
sensors 122 may be force-sensitive resistors, strain gauges, piezoelectric or piezoresistive
devices, pressure sensors, quantum tunneling composites, force-sensitive switches,
or other suitable devices. Force as utilized throughout the specification, including
the claims, refers to force measurements, estimates, and/or calculations, such as
pressure, deformation, stress, strain, force density, force-area relationships, thrust,
torque, and other effects that include force or related quantities. Optionally, force
information related to a detected touch may be utilized to select information, such
as information associated with a location of a touch. For example, a touch that does
not meet a force threshold may highlight a selection option, whereas a touch that
meets a force threshold may select or input that selection option. Selection options
include, for example, displayed or virtual keys of a keyboard; selection boxes or
windows, e.g., "cancel," "delete," or "unlock"; function buttons, such as play or
stop on a music player; and so forth. Different magnitudes of force may be associated
with different functions or input. For example, a lesser force may result in panning,
and a higher force may result in zooming.
[0021] The touch-sensitive display 118 includes a display area in which information may
be displayed, and a non-display area extending around the periphery of the display
area. The display area generally corresponds to the area of the display 112. Information
is not displayed in the non-display area by the display, which non-display area is
utilized to accommodate, for example, electronic traces or electrical connections,
adhesives or other sealants, and/or protective coatings around the edges of the display
area. The non-display area may be referred to as an inactive area and is not part
of the physical housing or frame of the electronic device. Typically, no pixels of
the display are in the non-display area, thus no image can be displayed by the display
112 in the non-display area. Optionally, a secondary display, not part of the primary
display 112, may be disposed under the non-display area. Touch sensors may be disposed
in the non-display area, which touch sensors may be extended from the touch sensors
in the display area or distinct or separate touch sensors from the touch sensors in
the display area. A touch, including a gesture, may be associated with the display
area, the non-display area, or both areas. The touch sensors may extend across substantially
the entire non-display area or may be disposed in only part of the non-display area.
[0022] In touch-sensitive displays 118 with touch sensors 114 that include both drive and
sense electrodes substantially on the same plane of the touch-sensitive display 118,
the sense electrodes include groups of conductors that may be spaced apart at locations
where the drive electrodes extend. The touch-sensitive display 118 includes a plurality
of drive electrodes 202-1, 202-2, 202-3, 202-4 (202 generally) and sense electrodes
204-1, 204-2 (204 generally) to detect touches on the touch-sensitive display 118.
Each section labeled as 202-1 is part of the same drive electrode 202-1. Each section
labeled as 204-1 is part of the same sense electrode 204-1. Other drive electrodes
and sense electrodes are labeled similarly in the drawings. The groups of conductors
are coupled together utilizing, for example, jumpers and wires to facilitate touch
sensing. The resistance of the drive electrodes 202 is typically highest where the
conductors of the sense electrodes 204 are closest together. The scanning rate is
affected by the resistance in the drive electrodes such that the scanning speed is
reduced with increasing resistance.
[0023] A top view of a section of the touch sensors 114 of a touch-sensitive display 118
of an electronic device 100 is shown in FIG. 2. The touch-sensitive display 118 includes
the drive electrodes 202-1, 202-2, 202-3, 202-4 and the sense electrodes 204-1, 204-2.
The sense electrodes 204-1, 204-2 include a plurality of conductors 206 that are coupled
together such that the sense electrodes 204-1, 204-2 generally extend substantially
across the entire width of the display area and, optionally, into the non-display
area. The drive electrodes 202-1, 202-2, 202-3, 202-4 extend between the conductors
206 that are coupled together such that the drive electrodes 202-1, 202-2, 202-3,
202-4 extend substantially across the entire length of the touch-sensitive display
118 and, optionally, into the non-display area. The drive electrode 202-1 is spaced
from the drive electrode 202-2 by spaces 216 such that the drive electrode202-1 is
not electrically connected to the drive electrode 202-2. The drive electrode 202-2
is also spaced from the drive electrode 202-3, and the drive electrode 202-3 is spaced
from the drive electrode 202-4, and so forth.
[0024] The touch-sensitive display 118 includes a plurality of such drive electrodes 202-1,
202-2, 202-3, 202-4 and sense electrodes 204-1, 204-2 in a repeating pattern. The
drive electrodes 202-1, 202-2, 202-3, 202-4 and the sense electrodes 204-1, 204-2
are disposed substantially on the same plane of the touch-sensitive display 118. Parts
of four drive electrodes 202-1, 202-2, 202-3, 202-4 and parts of two sense electrodes
204-1, 204-2 are illustrated in this example. The elements labeled 202-1 in FIG. 2
are part of one drive electrode, the elements labeled 202-2 are part of another drive
electrode, the elements labeled 202-3 are part of another drive electrode, and the
elements labeled 202-4 are part of yet another drive electrode. The elements labeled
204-1 in FIG. 2 are part of one sense electrode, and the elements labeled 204-2 are
part of another sense electrode. Thus, neither an entire drive electrode nor an entire
sense electrode is shown in FIG. 2, but rather sections of the electrodes 202-1, 202-2,
202-3, 202-4, 204-1, 204-2 are shown. The touch-sensitive display may include, for
example, 12 drive electrodes and 16 sense electrodes.
[0025] The conductors 206 comprise a plurality of members 208 of various shapes and sizes.
In this example, the conductors 206 include a central member and three members extending
from each side of the central member. Other shapes and orientations may be successfully
implemented. Ends of two of the members 208 of a conductor 206 are coupled to ends
of two of the members of the next or adjacent conductor 206 via jumpers 212.
[0026] The drive electrodes 202-1, 202-2, 202-3, 202-4 and the sense electrodes 204-1, 204-2
may be utilized to detect a touch by mutual-capacitance touch sensing. The controller
116 drives the drive electrodes 202-1, 202-2, 202-3, 202-4 to detect a touch such
that the drive signal is conducted through the drive electrodes 202-1, 202-2, 202-3,
202-4. The sense electrodes 204-1, 204-2 are utilized to detect changes in the signal
near locations where conductors are coupled together, while the drive electrodes 202-1,
202-2, 202-3, 202-4 are driven. To determine a touch location, the touch-sensitive
display 118 is scanned by driving the drive electrodes 202-1, 202-2, 202-3, 202-4
while signals from groups of conductors 206 that are coupled together are received
at the touch controller 116.
[0027] Spacers 210, also known as floating islands, are utilized between the sense electrodes
204-1, 204-2 and the drive electrodes 202-1, 202-2, 202-3, 202-4 to reduce cross coupling
between the drive electrode 202-2 and the conductor 302. The spacers 210 are not all
identical and have different shapes. The spacers 210 extend along edges of the conductors
206 such that four spacers 210 extend along edges of each conductor 206.
[0028] An expanded view of a section 214 of the touch-sensitive display 118 of the electronic
device 100 is shown in FIG. 3. In the expanded view of FIG. 3, touch sensors 116,
including part of the drive electrode 202-2 and parts of two conductors 206 including
a first conductor 302 and a second conductor 304 of the sense electrode 204-2 are
illustrated.
[0029] The first conductor 302 is a mirror image of the second conductor 304. The first
conductor 302 is operably coupled to the second conductor 304 by the jumper 212. The
two conductors 302, 304 are also coupled to other conductors as part of the sense
electrode 204-2 that extends across substantially the entire width of the display
area and, optionally, into the non-display area. The conductors 302, 304 may comprise,
for example, ITO disposed on a substrate or a part or layer of the touch-sensitive
display 118. The member 208 of the conductor 302 has two elongate edges, including
a first elongate edge 308 and a second elongate edge 310 on opposite sides of the
member 208. The first elongate edge 308 and the second elongate edge 210 extend from
the central member 208 to an outer edge 312 of the conductor 302. The second elongate
edge 310 is longer than the first elongate edge 308. In this example, the second 310
is on a bottom side of the conductor 302 and the first elongate edge 308 is on a top
side of the conductor 302. The outer edge 312 of the conductor 302 extends from an
outer end of the first elongate edge 308 to an outer end of the second elongate edge
310. The outer edge 312 extends at an obtuse angle from the first elongate edge 308
and is at an acute angle with the second elongate edge 310. A tip 314 of the conductor
302, where the second elongate edge 310 meets the outer edge 312, may be shaped such
that the tip 314 does not come to a sharp point. For example, the tip 314 may be rounded.
The conductor 302 is substantially a mirror image of the conductor 304. The conductor
302 is spaced from the conductor 304 such that the distance between the ends of the
first elongate edges 308 of the conductors 302, 304 is larger than the distance between
the ends of the second elongate edges 310 of the conductors 302, 304.
[0030] In this example, the spacers 210, include a first spacer 316 and a second spacer
318 that are utilized between the conductor 302 and the drive electrode 202-2. One
spacer 316 is spaced from the first elongate edge 308 and extends parallel to the
first elongate edge 308. The space between the spacer 316 and the conductor 302 is
small by comparison to the width of the conductor 302 or the width of the spacer 316.
The spacers 316, 318 may comprise, for example, ITO. The spacer 316 has a first edge
320 and a second edge 322 on opposite sides of the spacer 316. The first edge 320
and the second edge 322 extend from part of the spacer that extends along the central
member of the conductor 302 to an outer edge 324 of the spacer 316. The second edge
322 is longer than the first edge 320. In this example, the second edge 322 is on
a bottom side of the spacer 316 and the first edge 320 is on a top side of the spacer
316. The outer edge 324 of the spacer 316 extends from an outer end of the first edge
320 to an outer end of the second edge 322. The outer edge 324 extends at an obtuse
angle from the first edge 320 and is at an acute angle with the second edge 322. The
second edge 322 of the spacer 316 is spaced from and extends parallel to the first
elongate edge 308 of the conductor 302. The spacer 316 is generally parallel to the
conductor 302 along the length of the first elongate edge 308.
[0031] The spacer 318 is spaced from the second elongate edge 310 of the conductor 302 and
extends parallel to the second elongate edge 310. The space between the spacer 318
and the conductor 302 is substantially the same as the space between the spacer 316
and the conductor 302. The width of the spacer 318 is substantially the same as the
width of the spacer 316. The spacer 318 has a first edge 326 and a second edge 328
on opposite sides of the spacer 318. The first edge 326 and the second edge 328 extend
from part of the spacer that extends along the central member of the conductor 302
to an outer edge 330 of the spacer 318 shown in FIG. 3. The first edge 326 is longer
than the second edge 328. In this example, the first edge 326 is on a top side of
the spacer 318 and the second edge 328 is on a bottom side of the spacer 318. The
outer edge 330 of the spacer 318 extends from an outer end of the first edge 326 to
an outer end of the second edge 328. The outer edge 330 extends at an acute angle
from the first edge 326 and is at an obtuse angle with the second edge 328. The first
edge 326 of the spacer 318 is spaced from and extends parallel to the second elongate
edge 310 of the conductor 302. The spacer 318 is generally parallel to the conductor
302 and does not extend along the entire length of the second elongate edge 310 of
the conductor 302 such that the conductor 302 extends beyond the spacer 318.
[0032] The spacers 332, 334 are utilized between the conductor 304 and the drive electrode
202 to reduce cross coupling between the drive electrode 202 and the conductor 304.
The spacers 332, 334 near the second conductor 304 are substantially mirror images
of the spacers 316, 318 near the first conductor 302. Thus, the second conductor 304
and the spacers 332, 334 near the second conductor 304 are substantially mirror images
of the first conductor 302 and the spacers 316, 318 near the first conductor 302.
[0033] An electrode jumper 212 is operably coupled to the conductor 302 and to the conductor
304 to electrically couple the conductors 302, 304. The electrode jumper 212 may comprise,
for example, ITO, and may be disposed on the substrate or the part or layer of the
touch-sensitive display 118 on which the drive electrodes 202-1, 202-2, 202-3, 202-4
and the sense electrodes 204-1, 204-2 are disposed. The electrode jumper 212 may be
operably coupled to the conductors 302, 304, for example, by wires that extend into
another plane of the touch-sensitive display 118, above the drive electrodes 202-1,
202-2, 202-3, 202-4, such that the wires do not interrupt or break the drive electrode
202. The electrode jumper 212 is generally elongate and, in this example, is generally
V-shaped or chevron shaped. A first wire 338 is coupled to the electrode jumper 212
at or near one end 340 of the electrode jumper 212. The first wire 338 is also coupled
to the conductor 302 at or near its tip 314. A second wire 342 is coupled to the electrode
jumper 212 at or near an opposite end 344 of the jumper 212. The second wire 342 is
also coupled to the conductor 304 at or near its tip 346. Thus, the drive electrodes
202 do not extend under the electrode jumpers 212, although the drive electrodes 202
extend under or below the wires 338, 342.
[0034] The electrode jumper 212 is offset from the tips 314, 346 of the conductors 302,
304 such that the electrode jumper 212 is not disposed directly between the tips 314,
346 of the conductors 302, 304. The conductors 302, 304 are aligned with other elements
of the touch-sensitive display 118 such that a pixel electrode, for example, is aligned
with the space between the tips 314, 346 of the conductor 302 and the conductor 304.
By offsetting the electrode jumper 336, the electrode jumper 212 is not aligned with
the pixel electrode and the optical qualities of the touch-sensitive display 118 are
not negatively impacted or affected.
[0035] The drive electrode 202 extends around the electrode jumper 212 and between the conductors
302, 304. The drive electrode 202 does not extend between one spacer 316 and the conductor
302 or between the other spacer 318 and the conductor 302. The drive electrode 202
also does not extend between the mirror spacer 332 and the mirror conductor 304 or
between the other mirror spacer 334 and the mirror conductor 304. The spacers 316,
318, 332, 334 are not actively utilized during touch sensing.
[0036] Utilizing sense electrodes that include a longer elongate edge and a shorter elongate
edge, the space between the sense electrodes is generally increased by comparison
to sense electrodes of other devices. Thus, the width of the drive electrode is relatively
large, with the exception of a very small section of the drive electrode. The resistance
in the drive electrode described above is reduced and is relatively small compared
to a drive electrode that is not as wide. Lower resistance in drive electrodes facilitates
increased scanning speed.
[0037] The terms top, bottom, left, and right are utilized herein to refer to the orientation
of the elements illustrated in the drawings and are not otherwise limiting.
[0038] The present disclosure may be embodied in other specific forms without departing
from its spirit or essential characteristics. The described embodiments are to be
